Confused about loops - David Nahmani book

I bought LE8 the other day, and I'm trying to go through David Nahmani's excellent book.
In the first chapter - building the 'My New Day' song - you have to insert some loops including 'Deep Electric Piano 05' from the loop browser. Now I only seem to have 'Deep Electric Piano 01' which just doesn't sound right!
Yet, if I load the pre-done version from the book's DVD, then the 05 one is there and sounding good.
Now, I have (I think!) installed the loops from the DVD by dragging the correct folder to the loop browser.
Anyone got any ideas on this?
Now I know there are differences between LE and Logic Pro, but I think this is supposed to work.
Thanks.

OK, I sorted it out. I hadn't downloaded the complete Garageband loop pack.

APTS David Nahmani book Region Repeat - book results diff then mine

When I repeat regions as on Page 29,30 of the Apple Pro Training Series Logic Pro 8 book the regions are copied flush against the original regions INSTEAD of the way the book shows it which is the two regions are separated by an empty bar each. "Orchestra Strings" on track 4 Bar 9 and "Wild Slide Distortion" on track 5 Bar10 get copied to Bar 11,12 and 13,14 respectively in the book. My region repeat copied to Bar 10,11 and 11,12 respectively. I selected copies (2) and adjustment (BAR) and (as copies) in the dialog box. If I select adjustment (None) or (Auto) it does what the book shows. Anybody know what's going on here?
Dave

Hello.
I took the Level 1 certification course in which we used that book. There were a few errors in the book and I don't remember what they were, but that might be one of them. You con reach the author by doing a Google and finding his web site. He runs a Logic users group.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. My iBook library does not show up in iTunes.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. Some of my iBooks show up in my iTunes but they are "grayed" out. The only books that respond in iTunes are audiobooks and that's not what I'm looking for. Is this a stupid question?

Nevermind - I answered my own question, which is I CAN"T READ ANY BOOKS I purchased in iBooks on my MacBook Pro. If I want to read on my mac I have to use Kindle or Nook. Which means any book I've already purchased through iBooks has to be read on my iPad. Kind of a drag because there are times when it's more convenient for me to read while I'm sitting with my Mac.

Confusion about Kodo and JCA

Hi,
I'm a bit confused about Kodo's Connection Architecture strategy. It is my understanding that
PMF's can be built to use the connection architecture. Along this line, one would configure the
ConnectionFactory or ConnectionFactoryName, and possibly the ConnectionFactory2 and
ConnectionFactory2Name properties in a PMF. The result of the PMF implementation supporting the
connection architecture is nice integration with the application servers in terms of security,
transaction, and connection management. One can lookup in JNDI a reference to a Kodo PMF that
supports datastore transactions or to another one that supports optimistic transactions or to
another one that supports NTR, and with proper settings of the transactional properties and suitable
application code, one's sesson bean will work.
But from what I can see of Kodo's JDOPersistenceManagerFactory class, it, itself, implements the
ManagedConnectionFactory interface, meaning, I think, that this class is resource adaptor. And that
the part that confuses me. Why would Kodo be a resource adaptor? I thought it used a resource
adaptor, which I think is the same thing as a connection factory.
Anyway, I'm puzzled, and I'm hoping that someone could straighten me out.

David-
The fact that Kodo can integrate into an application server as a
Resource Adaptor, and section 3.2.2 of the specification that says that
the PersistentManagerFactory should be able to utilize a Resource
Adaptor to obtain connections to the data store are two separate issues.
We implement Kodo itself as a Resource Adaptor in order to provide ease
of integration into recent application servers. Your confusion is
understandable, since we do not actually yet support the use of Resource
Adaptors as the Connection Factories as per section 3.2.2.
Does that make sense?

Suggestion about writing a j2me Bookُ

i want to write a book about j2me(not english) . I am confused about what topics really need to be covered. it won't be a reference book but a book with 300 pages that makes developers to enter j2me mood.
I am posting my intended index of the book. Please let me know if you feel that a subject is not important to be covered or there is a subject that should be covered.
Thanks!
introduction to j2me
introduction to CLDC and MIDP
Architecture of a MIDP application
high level user interface and events
data persistency
low level user interface
generic connection framework
optimizing j2me apps
internationalization
bluetooth and obex
SMS and MMS
Quick introduction to java programming language(Appendix)
Sample Project(Appedix)

what do you think about adding an introduction
to wireless networks and/or m-commerce?I would think that your 2 introductory chapters would tell the readers just about everything they could do with j2me, kind of make them go -- Hey, if I can learn this stuff, I can do that! -- might even be a selling point, I at least glance though the opening chapters when I'm deciding which book to buy.
That said, I would suggest that you go easy on any restricted API that requires a signed jar --- digital signatures don't come cheap, and your book seems to be targetted at pre-beginners who wouldn't need details on stuff they wouldn't even be able to test without a signature.
Enough that they know it can be done, but that they can see results only on the emulator, not in the real world.
Yes, a couple of simple examples on these topics might be well received -- but, within your 300 pages, not at the cost of stuff that the reader can actually build, install and use.

Confused about color vs. b/w photos for printing...and more

I reading confusing things about exporting a PDF for printing with both color and black and white images used in the same document.
If I export to PDF and do a soft-proof and it looks okay, is that sufficient? If so, what's confusing about that, since this is my first print project, which Simulation Profile do I use? Is there a chart somewhere that compares U.S. Web Coated (SWOP) v2 to let's say 80 lb Gloss book with Aqueous coating (C2S)?
I don't know what any of this means. So, is there a good article on this site, elsewhere, or an online printer who can help a rookie like me ensure I end up with a decent product?
UPrinting.com advertises a "Free Project Review" that includes the following:
Our team will run your file through a 30-point inspection, covering technical issues including:
Artwork dimensions
Bleed setup
Low resolution images
Elements that are not within the safe zone
Image clipping
Font sizes
Un-embedded fonts
Folding setup
Page scaling
Line weights
Proper text spacing (compressed/expanded)
Narrow borders that are at risk of being cut
Compliance with USPS Mailing Guidelines
Bindery setup for multi-page artwork
What should I do? Is this trustworthy as long as I get a contract proof? Is there a "Go To" online printer that everyone loves (not sure you can recommend that here) or should I seek out a local printer?
I'm using CS4 and have a file that's (maybe) ready to go but am looking at a learning curve of days if not weeks if I have to figure it all out myself.
Thanks everyone.
Paul

InDesign puts grayscale and B&W (bitmap mode) art on the Black plate, where it belongs, so if you soft proof using the CMYK profile for your expected output conditions your preview will be accurate for the grayscale and B&W images as they will appear in print. presuming your monitor is calibrated and profiled so that you can trust what you see.
Aqueous coating is applied AFTER the printing to protect, and possible enhance the glossiness of, the page (but not all coatings are glossy). This is not the same thing as printing on coated paper, which has a glossy surface and high ink holdout (and improves detail reproduction and usually will geive better color). You should be using whatever profile the printer has specified.

Working through David's book - trouble with Control-Left/Right Arrow

I have worked my way through David Nahmani's book in the Apple Pro Training series and it is EXCELLENT! It's the best investment I've made in a long time. The investment I made in the new computer and software would be so much less AWESOME had I not found this little gem. I do have a question, though...
When it comes to the command keys, I can't get the Control-Left/Right Arrow commands to work. They are supposed to be zoom keys - but they just wipe my window left and right. I'm probably doing something wrong. Anyone know what it is?
Thanks in advance for your help.
Gina

Gina,
The problem is that Control + Arrow Keys is the default key command to switch between Spaces (window sets) in Leopard. So, here's what you do:
1. Open System Preferences
2. Click on "Exposé & Spaces" (top row, fourth icon from the left)
3. Click on the "Spaces" tab
4. In the bottom portion of the window you'll see a section for "Keyboard and Mouse Shortcuts", in the second pulldown menu change the setting from "^ Arrow Keys" to another of the choices. I personally use the second choice, which is Command + Option + Arrow Keys.
Now, back in Logic your Control + Arrow Keys should be controlling your Arrange window zoom.
Hope this helps!

Confused about how to display a rectangle on JFrame

i'm a little confused about how to display a rectangle on a jframe.
I know there is a class called Rectangle. is there a way to use it to display a rectangle on a JFrame? i couldn't find a way to do that.
i found a way to display a rectangle in the internet:
CODE:
public class RectangleFrame extends JFrame {
    public RectangleFrame() {
        super("My Rectangle");
        setSize(300,400);
        setLocation(300,300);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        JButton button = new JButton("Button");
        JPanel panel = new JPanel();
        panel.add(button);
        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(new Rect(), BorderLayout.CENTER);
        getContentPane().add(panel, BorderLayout.SOUTH);
        setVisible(true);
    public static void main(String[] args) {
        new RectangleFrame();
public class Rect extends JComponent {
    public void paint(Graphics g) {
        g.drawRect(50,50,200,200);
}is this the only way to do that? isn't there an easier way? do i have to write this new class Rect i wrote?
i don't really know how this Rect class i wrote works. could someone explain?
then another question: can i put a rectangle on a JPanel or do i have to add it directly onto the ContentPane as i did above?
i hope everything i asked is clear enough.
thanks for your effort.

Confuse about the injecting entity in EJB 3.0?

Hi all,
I have an customersBean which is inherit from customersRemote and my problem is i' am little confuse about injecting the entity(customer).
Where can you apply the EntityManagerFactory is it outside on EJB or Inside the EJB? means outside EJB is use the web application or java application. i have and example.
this is inside on EJB...............
public class CustomersBean implements com.savingsaccount.session.CustomersRemote {
@PersistenceContext(unitName="SavingAccounts")
EntityManagerFactory emf;
EntityManager em;
/** Creates a new instance of CustomersBean */
public CustomersBean() {
public void create(int id, String name, String address, String telno, String mobileno)
try{
//This is the entity.
Customer _customer = new Customer();
_customer.setId(id);
_customer.setName(name.toString());
_customer.setAddress(address.toString());
_customer.setTelno(telno.toString());
_customer.setMobileno(mobileno.toString());
em = emf.createEntityManager();
em.persist(_customer);
emf.close();
}catch(Exception ex){
throw new EJBException(ex.toString());
in web application, i'm using the @EJB in customer servlets.
public class CustomerProcessServlet extends HttpServlet {
@EJB
private CustomersRemote customerBean;
blah blah inject directly coming request field from jsp.
}

Confused about logical table source

Hi,
I'm confused about logical table source(LTS), there are 'General', 'Column Mapping', 'Content' tabs in
LTS, in General tab ,there are some information,like 'Map to there tables' and 'joins',
just here, we have created relationships in physical layer and BMM layer, so I would like to ask what's the use of the 'joins' here?

Hi Alpha,
Valid query, when you establish a complex join it is always between a logical fact and dimension table.Consider a scenario,
Example:w_person_dx is an extension table not directly joined to a fact but joins to a dimension w_person_d.
When you model the person_d tables in BMM, you ll have a single logical table with w_person_d as source.If you have to pull columns from both w_person_d and w_person_dx tables in a report, you add dx table as inner join to persond table in the general tab.Now when you check your physical query, you can see the inner join fired between the two dimensions.
Rgds,

Confused about transaction, checkpoint, normal recovery.

After reading the documentation pdf, I start getting confused about it's description.
Rephrased from the paragraph on the transaction pdf:
"When database records are created, modified, or deleted, the modifications are represented in the BTree's leaf nodes. Beyond leaf node changes, database record modifications can also cause changes to other BTree nodes and structures"
"if your writes are transaction-protected, then every time a transaction is committed the leaf nodes(and only leaf nodes) modified by that transaction are written to JE logfiles on disk."
"Normal recovery, then is the process of recreating the entire BTree from the information available in the leaf nodes."
According to the above description, I have following concerns:
1. if I open a new environment and db, insert/modify/delete several million records, and without reopen the environment, then normal recovery is not run. That means, so far, the BTree is not complete? Will that affact the query efficiency? Or even worse, will that output incorrect results?
2. if my above thinking is correct, then every time I finish commiting transactions, I need to let the checkpoint to run in order to recreate the whole BTree. If my above thinking is not correct, then, that means that, I don't need to care about anything, just call transaction.commit(), or db.sync(), and let je to care about all the details.(I hope this is true :>)
michael.

http://www.oracle.com/technology/documentation/berkeley-db/je/TransactionGettingStarted/chkpoint.html
Checkpoints are normally performed by the checkpointer background thread, which is always running. Like all background threads, it is managed using the je.properties file. Currently, the only checkpointer property that you may want to manage is je.checkpointer.bytesInterval. This property identifies how much JE's log files can grow before a checkpoint is run. Its value is specified in bytes. Decreasing this value causes the checkpointer thread to run checkpoints more frequently. This will improve the time that it takes to run recovery, but it also increases the system resources (notably, I/O) required by JE.

Confused about extending the Sprite class

Howdy --
I'm learning object oriented programming with ActionScript and am confused about the Sprite class and OO in general.
My understanding is that the Sprite class allows you to group a set of objects together so that you can manipulate all of the objects simultaneously.
I've been exploring the Open Flash Chart code and notice that the main class extends the Sprite class:
public class Base extends Sprite {
What does this enable you to do?
Also, on a related note, how do I draw, say, a line once I've extended it?
Without extending Sprite I could write:
var graphContainer:Sprite = new Sprite();
var newLine:Graphics = graphContainer.graphics;
And it would work fine. Once I extend the Sprite class, I'm lost. How do I modify that code so that it still draws a line? I tried:
var newLine:Graphics = this.graphics;
My understanding is that since I'm extending the Sprite class, I should still be able to call its graphics method (or property? I have no idea). But, it yells at me, saying "1046: Type was not found or was not a compile-time constant: Graphics.

Thanks -- that helped get rid of the error, I really appreciate it.
Alas, I am still confused about the extended Sprite class.
Here's my code so far. I want to draw an x-axis:
package charts {
    import flash.display.Sprite;
    import flash.display.Graphics;
    public class Chart extends Sprite {
        // Attributes
        public var chartName:String;
        // Constructor
        public function Chart(width:Number, height:Number) {
            this.width = width;
            this.height = height;
        // Methods
        public function render() {
            drawAxis();
        public function drawAxis() {
            var newLine:Graphics = this.graphics;
            newLine.lineStyle(1, 0x000000);
            newLine.moveTo(0, 100);
            newLine.lineTo(100, 100);
I instantiate Chart by saying var myChart:Chart = new Chart(); then I say myChart.render(); hoping that it will draw the axis, but nothing happens.
I know I need the addChild method somewhere in here but I can't figure out where or what the parameter is, which goes back to my confusion regarding the extended Sprite class.
I'll get this eventually =)

Confused about standby redo log groups

hi masters,
i am little bit confuse about creating redo log group for standby database,as per document number of standby redo group depends on following equation.
(maximum number of logfiles for each thread + 1) * maximum number of threads
but i dont know where to fing threads? actually i would like to know about thread in deep.
how to find current thread?
thanks and regards
VD

is it really possible that we can install standby and primary on same host??
yes its possible and i have done it many times within the same machine.
For yours confusion about spfile ,i agree document recommend you to use spfile which is for DG broker handling if you go with DG borker in future only.
There is no concern spfile using is an integral step for primary and standby database implementation you can go with pfile but good is use spfile.Anyhow you always keep pfile on that basis you created spfile,i said you make an entry within pfile then mount yours standby database with this pfile or you can create spfile from this pfile after adding these parameter within pfile,i said cause you might be adding this parmeter from SQL prompt.
1. logs are not getting transfered(even i configure listener using net manager)
2.logs are not getting archived at standby diectory.
3.'ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION' NEVER COMPLETE ITS RECOVERY
4. when tried to open database it always note it 'always' said system datafile is not from sufficiently old backup.
5.i tried 'alter database recover managed standby database camncel' also.Read yours alert log file and paste the latest log here..

Confused about SOAP

Hi all,
As far as I know, SOAP is initially designed to be an XML based
RPC protocol.
But Java API for XML Messaging (JAXM), which is actually a
messaging API (and not RPC), is also based on SOAP.
How do they fit to each other?
In a few words, what does actually SOAP define?
I am confused about that, can you help me?
Any idea will be appreciated.
Thank you

In a few words -- no. Try here:

Confused about passing by reference and passing by valule

Hi,
I am confuse about passing by reference and passing by value. I though objects are always passed by reference. But I find out that its true for java.sql.PreparedStatement but not for java.lang.String. How come when both are objects?
Thanks

Hi,
I am confuse about passing by reference and passing
by value. I though objects are always passed by
reference. But I find out that its true for
java.sql.PreparedStatement but not for
java.lang.String. How come when both are objects?
ThanksPass by value implies that the actual parameter is copied and that copy is used as the formal parameter (that is, the method is operating on a copy of what was passed in)
Pass by reference means that the actual parameter is the formal parameter (that is, the method is operating on the thing which is passed in).
In Java, you never, ever deal with objects - only references to objects. And Java always, always makes a copy of the actual parameter and uses that as the formal parameter, so Java is always, always pass by value using the standard definition of the term. However, since manipulating an object's state via any reference that refers to that object produces the same effect, changes to the object's state via the copied reference are visible to the calling code, which is what leads some folk to think of java as passing objects by reference, even though a) java doesn't pass objects at all and b) java doesn't do pass by reference. It passes object references by value.
I've no idea what you're talking about wrt PreparedStatement, but String is immutable, so you can't change its state at all, so maybe that's what's tripping you up?
Good Luck
Lee
PS: I will venture a guess that this is the 3rd reply. Let's see...
Ok, second. Close enough.
Yeah, good on yer mlk, At least I beat Jos.
